1. A speaker device comprising:
a base defining an xy-plane;
a housing connected to the base such that the housing extends from the base in a z-direction relative to the xy-plane, the housing:
having a generally rectangular cuboid shape with rounded edges and corners;
having a height in the z-direction, a width in an x-direction, and a depth in a y-direction, the width being greater than the depth, the height being greater than the width; and
including a front housing member and a rear housing member that are attached together along an xz-plane, the front housing member including openings that enable passage of audio waves;
multiple speaker modules disposed within the housing in a stacked orientation in the z-direction, each of the multiple speaker modules oriented to face toward the front housing member; and
an internal structural housing wherein the multiple speaker modules are housed within the internal structural frame between the front and rear housing members, wherein:
the internal structural frame includes a front component and a rear component that differ from one another in one or more of material, density, thickness, or weight; and
the front component includes apertures that conform to speaker drivers of the multiple speaker modules.
